SMA-JK M/F Fixed Coaxial Attenuator — DC to 4 GHz, 10 W, 50 Ω, selectable 1–30 dB Key benefits - Wideband coverage: Operates from DC to 4 GHz so a single attenuator works across multiple RF bands, reducing the need for different parts for different frequencies. - Protects equipment and preserves signal integrity: 10 W power handling lets the attenuator absorb higher-power signals without distortion or damage, preventing receiver overload and protecting test equipment. - Low-reflection performance: 50 Ω impedance minimizes reflections and standing waves, improving measurement accuracy and system stability. - Flexible attenuation choices: Available in fixed values of 1, 3, 6, 10, 15, 20, and 30 dB to provide reliable, repeatable signal reduction for a range of applications. What it does and why you need it - Accurately reduces RF signal levels to match downstream component limits, calibrate test setups, or set known input levels for measurement and characterization. - Minimizes mismatch-related errors in test and production environments by maintaining a consistent 50 Ω coaxial interface. - Handles moderate CW and pulsed power (10 W) so it can be used with many bench and system-level transmitters without immediate risk of damage. Compatibility and form factor - Connector type: SMA-JK M/F (SMA jack male/female configuration as specified), compatible with standard SMA coaxial cabling and equipment. - Coaxial fixed attenuator designed to integrate directly in-line with SMA systems for straightforward use in labs and installations. Performance highlights - Frequency range: DC to 4 GHz - Power handling: 10 W - Nominal impedance: 50 Ω - Attenuation options: 1, 3, 6, 10, 15, 20, 30 dB - Function: Fixed attenuation for stable, repeatable signal reduction Typical applications - RF test and measurement: Use in labs to set predictable input levels for spectrum analyzers, network analyzers, and receivers. - System protection and calibration: Protect sensitive receiver front ends and ADC inputs from high-power signals or calibrate transmit/receive chains. - Signal conditioning in communication equipment: Control signal amplitudes in prototypes, production testing, or field installations where DC–4 GHz coverage is required. Why choose this attenuator - Simple, reliable fixed attenuation choices and a standard SMA-JK M/F coaxial interface make it easy to deploy in test benches and RF systems. - Designed to reduce reflections and handle up to 10 W, providing a balance of performance and protection for many common RF tasks.
